Gypsum self-leveling mortar manufacturing method
The invention discloses a gypsum self-leveling mortar manufacturing method which comprises the following steps: raw material preparation: raw materials comprise 600 to 700 parts of desulfurized gypsum, 100 to 150 parts of phosphogypsum, 30 to 50 parts of heavy calcium powder, 30 to 50 parts of dried sand, 50 to 70 parts of 525 cement, 2.5 to 3.5 parts of a water reducing agent, 1 to 1.5 parts of a retarder, 0.5 to 0.8 part of a rheological additive, 0.3 to 0.5 part of low-viscosity cellulose ether, 0.5 to 0.8 part of polyvinyl alcohol and 1 to 1.5 parts of a defoaming agent; and raw material screening: screening the powder materials one by one through a screening device to remove impurities of the raw materials. The low-viscosity cellulose ether is added into the raw materials, fusion of other raw materials in the mortar is facilitated through fusion of the low-viscosity cellulose ether, all the raw materials in the mortar are fully fused, the hardness of the formed mortar is improved, and the problems that existing gypsum mortar is low in hardness and poor in performance are solved.
本发明公开了一种石膏自流平砂浆制作方法，包括以下步骤：原料准备，原料包括脱硫石膏600‑700份、磷石膏100‑150份、重钙粉30‑50份、烘干砂30‑50份、525水泥50‑70份、减水剂2.5‑3.5份、缓凝剂1‑1.5份、流变助剂0.5‑0.8份、低粘纤维素醚0.3‑0.5份、聚乙烯醇0.5‑0.8份和消泡剂1‑1.5份；原料筛选，将上述中的粉料通过筛选装置进行一一筛选，将原料的杂质筛除。本发明中通过在原料中添加低粘纤维素醚，通过低粘纤维素醚的融入便于辅助砂浆中其它原料的融合，是砂浆中的各种原料充分融合，提高了砂浆成型后的硬度，解决了现有的石膏砂浆硬度低性能差的问题。
